9 The Technology is HERE!!!

10 5 Ingredients for Triple Play Success Copper video Data Voice video IP Fiber:  Loop Fiber  FTTc to FTTp ADSL2+:  Today technology  Copper re-use Pure Packet”  Head end  Internet  Encoder to access  Cost + integration IGMP:  Imbedded in access  Distributed In-Home  Lower CPE costs  Less wiring  Easy installation

11 Pure Packet Network - Middleware Middleware Set Top Box Ported to API on STB Operating System Ported to API on STB Operating System Integrated to Middleware Conditional Access System VOD - PVR Integrated to Middleware Considerations  Thick or thin client  Memory requirements  Processing needs  Box features Vs. middleware applications  3 rd party vendors/applications supported

12 What you should know about IGMP  IGMP was not originally intended for video/channel changing For data Internet multicast UDP static state: No means of authentication  IGMP standard requires a number of compromises  Not all IGMP is implemented the same: therefore performance varies Full implementation IGMPv2 with DIM-PM (Routers) Access IGMPv2 management with IGMP proxy Access ‘pass-through’ with IGMP Snooping  IGMP involves no security for content Does not identify or care what device sends a join  IGMP joins and leaves frequently get out of balance (dropped/overflows) No automatic method in IGMP standard to “clean up” multicast IGMP is to video what Dial Tone is to POTS
